Chapter 7 MIDI and Sound Synthesis: 7.1

Overall this chapter is by far the most practical and most successfully written one. It gives very detailed information covering the physical structure of MIDI, how it works on a high level of abstraction, how to create our own synthesizer sounds etc. Along with the learning supplements, this chapter definitely stands out from others. I feel I’m biting the real meat of this text.

7.1 Concept

7.1.1, The Beginning of Sound Synthesis, is two and a half pages long, and since it is not THAT closely related to the actually work, it is very easy to get dry and be skipped. But we’ve already put so many words in it, why don’t we use more pictures of the electrical instruments mentioned to walk the readers through the history of sound synthesis? (say, we mentioned MIDI controller, but some readers might not know what a controller is until 7.1.2.)

7.1.2, MIDI Components, talks about various meanings of MIDI and gives an example of a setup for recording and editing MIDI on a computer. However, if we could move Figure 7.5 to the front of the bullets, or insert another figure showing the entire structure, the readers would have a concept of the whole picture before they start going into the details and getting lost somewhere 2 pages later. And we really need to move Figure 7.6, the 5-pin DIN connection for MIDI, away from the end of this section since it is an example of earlier material, but we already summarized the section in the paragraph above it.

7.1.3, MIDI Compared to Digital Audio, is pretty well written. I don’t have much to say. Maybe mention that we will discuss Note On message later in 7.1.5.2? Actually we might not even need to mention the data bytes until later.

7.1.4, Channels, Tracks, and Patches in MIDI Sequencer, is very straight forward. I have nothing much to say about this section except it has a typo in the first sentence before the word “track,” and some figures in this chapter are a little bit hard to read. For example, Figure 7.13, I have to zoom in A LOT to see what’s going on in the picture, and this can be easily solved by cutting off part of the right end of this picture.

7.1.5, A Closer Look at MIDI Messages, is the most mathematical and theoretical section in 7.1. First, can we possibly change the name for this section? “A Closer Look” just doesn’t sound right. In 7.1.5.1, a figure showing the conversion among binary, decimal and hexadecimal numbers is needed, or we can refer the reader to the previous section on binary.

I do not have much comment on 7.1.6, just Figuare 7.17 is a little hard to read.

7.1.8, Synthesizer Components, gives brief description of each component within the synthesizer, and the practice exercise in 7.1.9 wraps everything up. As these two sections are not finished yet, I am looking forward to reading the completed version.

"Dynamite" proved to be more difficult than we anticipated, making it kind of a horrible song to choose. Anqi and I laid down the first verse and it has so many layers! We started getting very frustrated trying to select patches and combine everything- I have a newfound appreciation for music producers! Despite our frustrations, I feel like we're really learning a lot about Reason through this practical albeit difficult exercise. I think Anqi and I are going to go back to reading and then work on "Dynamite" starting tomorrow am. Time to REBOOT!

June 30

What an awesome day.
Jordan and I spend basically the entire day working on creating a karaoke track to Rebecca Black's "Friday". We've created the basic backtrack for the intro, verses, and chorus, but have yet to install the vocal background. http://www.youtube.com/watch?v=9u9-AdPAOy0
I also have polished off chapter 7, and am looking forward to presenting our work tomorrow. The other groups are hard at work getting their projects started. This was a really fun project to work on because it let me practice my listening skills, and Jordan was able to help me put what I heard into the software. What I found interesting was that while I was able to hear the basic chord progression and would get something "close enough", Jordan was much better able to hear the details of each and every note and whether they were correct. I don't know if that means that his listening is better than mine or if it means that I am more able to "fill in" what I need to hear based on a chord progression.
I did find sometimes that my vocabulary for music wasn't always totally appropriate for working with someone who wasn't classically trained. When I talk about hearing a "pedal tone" or start counting rhythms numerically or talking about the chord progression, I find myself needing to explain what I mean in a different way. I thought that was a good skill to learn, because it means I have to not only understand what I want to hear, but be able to express it in more than one way.

Finishing Chapter 7

I'm working through Chapter 7 right now, and I agree with Anqi- this chapter is really well-written overall. It manages to convey a lot of concepts clearly and makes great connections between the reading material and the software we're working with- very practical! I'm especially enjoying learning about samplers since we've been working with that so much in Reason.

Typo:
pg. 18- in the second paragraph, it reads "There can be than one audio sample associated with a single note." This should say "There can be MORE than one..."


After lunch, Anqi and I are going to start on our project! We we we so excited! :)

June 29th Finishing up Chapter 7 - Anqi

I finally finished up reading Chapter 7. It is definitely the most practical chapter we've read so far and overall the content is fairly well written. I am playing more with the learning supplements right now as I did not try them out thoroughly while reading. My plan is to finish the assessments for learning supplements asap, then start rereading this chapter again and write the evaluation (this is the first chapter that I had to actually take some notes to help me understand). Erica and I are definitely gonna start on the project tomorrow, even though I'm not really sure what we are supposed to do.

Have fun blogging!

June 29th

I'm working on Chapter 7. The song we picked to transcribe is When Love Takes Over and we should be done at the beginning of next week since we just started planning today. I am very excited for the final product!

7.1

7.1.1 - The Beginnings of Sound Synthesis

This was pretty interesting. There isn't much else to say. I did think it was kind of funny that yesterday I watched an episode of The Big Bang Theory that had a Theremin in it. That was helpful to visualize the instrument, since I saw it being used so recently. It was sort of fun to see how everything came together to come to the synthesized music we work with these days.

7.1.2 - Midi Components

It seems to me a little unnecessary to have the list of different meanings for MIDI at the beginning of this section and then almost repeat them soon after when giving real-life examples of the different meanings. Why not just condense this all by combining the two lists and save a little room?

Above the list of real-world examples on page 4, the Preface is mentioned when it should be chapter 1 that is mentioned. The Preface is mentioned again in the bullet point on page 4, at the top of page 5 it talks about figures from the preface. It should say figures from chapter 1. This is in the second bullet point.
Immediately below the aside on page 5, there is a typo. "If you don’t have a dedicate hardware of software..." Dedicate should be dedicated.

I feel like figure 7.3 should be placed directly below the second bullet point on page 5 instead of at the bottom of the page. It makes more sense, and wouldn't hurt anything.

In the first line on page 6, it references the Preface again, when it should reference chapter 1.

7.1.3 - 7.1.4

All of the sections so far in this chapter are pretty important to gaining a good basic understanding of MIDI and the differences between MIDI and digital audio. However, since we've been using the MIDI already, most of the information is just reinforcing knowledge we already have at this point.

7.1.5.1 - Binary, Decimal, Hex

I feel like since you spent time on binary, spending a little time, either in lecture or in the book, on hex would be a smart thing to do. It wouldn't take that much time, but if it is brought up like this I feel like it should be explained a little bit more.

7.1.5.2 - MIDI Message Types and Format

I think that it is important to know how MIDI works, and learning how the messaging behind a MIDI machine works is crucial to understanding MIDI. I think sections like this are important, but there really isn't anything that you can do with messaging. This makes it a little hard to stay focused.

7.1.6 - Synthesizers vs. Samplers

The first sentence in the second paragraph on page 18 says "There can be than one audio sample." I assume "more" should be placed after "can be."
At the bottom of the aside on page 19 the tails of the g and y are missing. This needs to be aligned better.

7.1.8 - Synthesizer Components

I thought this was a good section. The content was pretty practical to what we are doing, and along with the help that Jason gave us last Friday working with the synthesizers, I think I'm starting to understand how to manipulate them better. Some of this content was review, since we've been working with these machines for several weeks now. I was going to mention that I thought it would be good to have a supplement here, but then I saw the supplement in the next section! I was so, so, so excited.

7.1.9 - Creating your own Synthesizer sounds

The Reason supplement was great. I thought that it was the most practical supplement we've had so far and I had fun doing it. For some reason I couldn't get the sound to work with the subtractonaut supplement, so I didn't get that one finished.

Beginning of the week

So Monday I finished up the last bit of Chapter 5, finished the analysis and took the post test. After that, I started on Chapter 5 and worked my way through the first few sections. Nothing too interesting, but I heard a song on Pandora ("Like A Stone" by Audioslave) that I thought I could make with Reason and Sonar, so I started the drum beat for that at the end of the day. I got really interested in it and worked on it for most of Tuesday, and then for a little bit in the morning on Wednesday. I made it a decent way through the song and only have about a third of it left. I found it difficult to find the right chord when trying to translate guitar chords into sonar, so that took me a long time. Not having any real experience with chords made this pretty challenging for me, but with some online help I think I got all of the correct chords I needed. I'm pretty happy with what I have so far and I might come back after everyone is gone one day and lay down a vocal track for it - see if I still have any singing skills left! I've been having fun with it, but it is time to finish up Chapter 7 so I'll be waiting to finish that song until after I've finished 7.

Chapter 7

Today I continued reading Ch. 7 (which I started yesterday.) My goal is to finish the reading and evaluations today so I can begin work on duplicating one of the pop songs we've chosen. So excited for this new project!

June 28th Continued

Today I completed chapter 7, and have read through all of the supplemental activities. I have taken notes, and tomorrow morning I will come in and fill out all my evaluations. I want to be finished with the evaluations in the morning so that I can start working on a more fun project with a coworker. It's a little tricky to try to start that project, because not everyone finishes the reading at the same time. I also don't seem to have reason on my computer without the disk... and I don't know where the disk is. But tomorrow I will have audition, and I should be able to get started nomatter what my coworkers have finished.

June 28th

I read the article Computational Thinking in Music. It was really interesting to read how interconnected everything is... I am reading Chapter 7 all of the information is very practical. Tomorrow we will continue with REBOOT! and I am very excited to sing the melody.

June 28

Today I started out slow with my reading of Chapter 7. I do, however, think that this chapter is one of the most relevant to what our final project will become. Learning about exactly how to make samples and loop them is really great, because it will help us make the type of instruments we want later on. I also found the computation and composition article to be really interesting, because it deals with my favorite musical genres. Minimalism and 20th century experimentalism is one of my favorite areas of study, and many of the loops I've created imitate that style. Hopefully this afternoon I can finish reading Chapter 7 and move on to finishing the evaluations for each supplemental activity.

Monday, June 27, 2011

Today we spent the day working through chapter 7. In the morning I finished my chapter 5 assessment, took the chapter 5 postest and the chapter 7 pretest, and began reading. I'm well into chapter 7, and have pages of notes to use for my evaluations. We also made a list of three or four songs we think we could recreate. The day has been pretty quiet, as we all are trying to get through chapter 7 quickly so we can begin working on our other project.

June 27th Starting Chapter 7 - Anqi

Monday, a new cycle starts here. I finally caught up with my work on Chapter 5. As we are already split up into groups, and will be starting collaboration as soon as tomorrow, I am trying to finish chapter 7 asap. My goal today is to read as much of 7.1 as I can and I will blog tomorrow morning.

Chapter 5 Digitalization: 5.2 (To be Continued..)

5.2 Applications

5.2.1 Choosing and Appropriate Sampling Rate

5.2.1 explains why we choose sampling rates that are higher than the upper limit of human hearing, and talks about the tradeoff between sampling rates and file sizes. Overall this part is brief and informative.

Just out of curiosity, why do we pick 44100Hz as default sampling rate from the very beginning? I looked it up online later, but maybe we can briefly mention it somewhere.

5.2.2 Input Levels, Output Levels, and Dynamic Range

My first impression is that the last a couple of paragraphs are a little bit dry and hard to read.

Also, I don’t quite understand Figure 5.19. How can I tell no sample value is less than -90.3 dBFS from the picture? And in the Aside, the number 32768 might be random to most readers. It would be good to write it as 2^(16-1) since this is a 16-bit system.

5.2.3 Latency of Digital Audio Systems

With the help of Flash Tutorial: Reducing Latency, 5.2.3 does a pretty good job explaining what latency is and how to reduce it. However, without the flash tutorial, the part on buffer size is quite hard to understand, and it doesn’t explain the relationship between buffer size, sampling rate and latency well enough.

5.2.4 Word Clock

This part well explains the concept of word clock, which is pretty unfamiliar to most readers. The master vs. slave analog is very good. The Flash Tutorial: Word Clock is another success. I feel most learning supplements in this chapter are more helpful than the text itself.

Chapter 5 Digitalization: 5.3 and Review on 5.1 Part II

5.3.2 Sampling and Quantization in MATLAB

On Wednesday I reviewed 5.1.2.3 Bit Depth and Quantization Error. My day started with playing with MATLAB in hope of finishing up Experimenting with Quantization Error in MATLAB. I feel the language used in those programming exercises instructions is very different from other parts of the text. I've been having a hard time understanding what exactly the exercise is asking me to do. For example, I don't really understand what the average magnitude error is and the process of normalization. Even when I was checking the solution, I still don't quite understand what is going on. The information given in 5.3.2 is very limited for an exercise like this.

5.1.3 Digital Audio Formats and Transmission

This section is mostly informative. It does have practical purposes, but not that applicable to us at this point.

5.1.3.1 Audio Data Stream and Transmission Protocols

The beginning generally talked about the purpose of using transmission protocols, but a specific example with the devices mentioned in the previous chapters and how transmission protocols help might make this chapter not that disconnected from previous knowledge. Overall 5.1.3.1 delivers quite amount of information the readers might need. Just one point I didn’t really like: TOSLINK is for Toshiba-Link, even on its official website it reads like that. The TOShiba-LINK just makes me feel weird.

5.1.3.2 Signal Path in an Audio Recording System

My first impression was that the style of the figure in this part did not go along with any others in this text at all. But it is indeed very easy to read.

5.1.3.3 Digital Audio Types

Table 5.1, Common audio file types, is very helpful. I think to most readers, skimming though this part and referring to this table will fulfill their learning purposes.

June 24th

I was hoping to get my blog up to date today (gotta get better at that), but our little chat with Jason, Eric and Dr. Burg got me a bit distracted. I'll finish that up and submit the analysis on Sakai over the weekend.

I thought the talk at the end of Friday was good and really helped bring together some ideas. It was helpful to get more clear ideas of what we could do in Reason, Sonar and Finale. I think it set us up for a more directed path next week. I thought it was fun to work on Reboot this week, and now it seems like we have a bit more freedom and direction for where we could go with it.

The suggestion I have for the little mini side projects we discussed giving the students is to give a song a week for the first few weeks and make each one a little bit more complicated. That way people are learning the software more and more as time goes on, and by the time they are getting ready to make their own composition they will be quite comfortable with the software.

This week was definitely more social and I think we are getting more comfortable with each other, which is obviously a good thing.

5.2 sections

5.2.1 - Choosing an Appropriate Sampling Rate

This section is very practical, since having the right sample rate is crucial to recording a high quality sound. This section is well-written, and straight forward. I also thought it was interesting to read about the different reasons we would need to record above 20 kHz.

5.2.2 - Input Levels, Output Levels, and Dynamic Range

Like several of the sections in this chapter, I think that this section is quite practical. Learning about clipping and the different ways to avoid it is crucial for successful recording of audio. At the top of page 25, where it talks about the Bit Depth and Dynamic Range supplement, it mentions that the supplement is linked at the top of the section, but it is actually linked on page 25, right next to this sentence.

5.2.3.1 - Latency in a Live Performance

I feel like this section needs, a little bit more info on how to prevent this kind of latency, but there might just not be any more to say. I'm not sure, it just felt a little bit empty at the end of the section and I felt like there could have been some more detail there. Latency is a big issue, and even though live music production isn't necessarily as much of what this course is about, I feel like perhaps this could use a bit more content.

5.2.3.2 - Writing to the Hard Drive During Digital Audio Recording

This section does a really good job of explaining why it is important to use an external hard drive with firewire when working with digital sound recording. It kept it simple and I think anyone would be able to easily understand it. I think that it is possible that this section may be better placed in Chapter 1, but I can understand why it is placed here as well.

Page 28 mentions dynamic allocation of space in passing, but never mentions it again. I think there should be a little bit of an explanation of dynamic allocation of memory, if it is gonna be mentioned like this. No music major is going to understand what it is if it is just mentioned in passing like this.

5.2.3.3 - Latency, Drivers, and Buffer Size

This section is helpful and easy to understand. It covers the required content well and deals with the potential problems associated with latency as good as can be expected.

5.2.3.4 - Software Vs. Hardware Monitoring During Digital Audio Recording

All of these different sections on latency seem like a little bit of overkill, but at the same time it is clear that these different sections are different and all important in one way or another. Perhaps combining a few of them and condensing them would be better. I also feel like 5.2.3.4 should be placed right after 5.2.3.2. There's nothing wrong with this section, though.

5.2.4 - Word Clock


This is a good concept to end the section with, since it kind of brings all of the latency concepts together and deals with them all with basically one solution.


Conclusion

This chapter is very practical and important to understanding how to record or create a good audio track to/ on a computer. It got a bit dry at times, but I feel like most of the content is pretty important and worth reading if the student really wants to learn how to record and create quality audio tracks.

June 24th

I didn't want to be very behind next week so I just finished a lot more of my Sakai evaluation of Chapter 5. I can't wait to sing REBOOT I will be in the lab Tuesday and Wednesday. See you guys soon!

Thursday, June 23, 2011

June 23

I've been sitting here for the past few hours, trying to figure out how to use Reason's arpeggiator and Thor, and am getting kinda frustrated. I decided to try and brainstorm some ideas for the synth lead for "Reboot" instead. Beth and I also spent some time creating different drum loops/effects for The Research Team's first hit.

I'm continuing to read Chapter 5, even though I feel like most of the material is going straight over my head (especially 5.1.3.1... I have read that part several times, and it isn't becoming any more clear.) However, the learning supplements have really been helping, and I feel like most of this information could be clearly conveyed in a lecture.

June 23

Today I finished reading the new version of 5.2, and took notes in order to better evaluate it. I will hopefully get started on the evaluation (which will take a while, since I will need to sift through my notes) today. Erica and I are planning on tweaking "Reboot" so that we can hopefully have a semi-performable version at the beginning of next week to present. There are actually a lot of projects going now, and it would be nice to present them to each other at a set time during the week.... maybe we could do that ourselves? Just a thought.

June 23rd Not off a Good Start...

My day started with playing with MATLAB in hope of finishing up Experimenting with Quantization Error in MATLAB. I feel the language used in those programming exercises instructions is very different from other parts of the text. I've been having a hard time understanding what exactly the exercise is asking me to do. For example, I don't really understand what the average magnitude error is and the process of normalization. Even when I was checking the solution, I still don't quite understand what is going on. The information given in 5.3.2 is very limited for an exercise like this.

To make sure I can finish my work at least before the end of today and leave tomorrow more flexible, I'll first read 5.3.4 the Mathematics of Dithering and Noise Shaping, and then pick up from where I stopped on Tuesday, beginning of section 2. Hopefully by the end of the day I'll finish all the assessments for Learning Supplements on Sakai.

Chapter 5 Digitalization: 5.3 and Review on 5.1 Part I

5.1.2.2 Sampling and Aliasing

Mathematically, this part is very confusing to me, but with the help of the Flash Tutorial, I can visualize the phenomenon of aliasing better, but not sampling.

On page 4, under Figure 5.3, it stated “Figure 5.3 shows eight samples being taken for each cycle of the sound wave”, and then it talks about the frequency of the sound wave and sampling rate. And the next paragraph gave an example on aliasing. But I feel the process of sampling and phenomenon of aliasing could be explained better. I’d like to emphasize on the SAMPLING. If we want 8 samples in one cycle, we chose a sampling rate that is 8 times as high as the frequency of sound wave, thus given frequency of 440Hz, we need sampling rate of 8*440Hz, which is 3520Hz. We do NOT need to mention that the samples are stored as binary numbers right now since binary numbers will not be talked about until quantization, and it might cause confusion here. The reconstruction of sound wave is a process of the DAC fitting a sine wave on the sampled points (I’m not 100% sure on this part, but it must be some kind of fitting through some numerical methods, say, starting from fitting the sine wave of 20Hz, the lowest frequency human ears can hear, and increasing the frequency until all the samples can be fitted), which means, we need at least 2 samples per cycle to reconstruct the original sound wave; that is a sampling rate of at least twice as high as the frequency of the original sound wave; this is also the core meaning of the Nyquist Theorem. THEN we can say that IF the sampling rate is not high enough, aliasing will happen, followed by an example of aliasing.

In the figures, I hope the fact that the samples are measured at “equally-spaced moments in time“ will be emphasized. Figure 5.3 is definitely not only a graph of a 440Hz sound wave, it also shows the samples measured at every 1/(440*8) seconds.

At the end of 5.1.2.2 we can say refer to 5.3.1 for the algorithms for aliasing.

5.3.1 Mathematics and Algorithms for Aliasing

I have to admit that I see the algorithms, but the examples given are just NOT helpful since they only demonstrate how WE draw the graphs, but not how the graphs are actually generated in the process of sampling. The algorithm is NOT what causes the problem. It is the omission of necessary sampled points that lead to the error.

Figure 5.28 should be called 1760Hz wave aliased to a 240Hz wave due to being sampled at 1000Hz, because obviously there are two waves in it, and the 1760Hz one is not as important as the 240Hz one, plus there is a typo that it’s Hz not kHz.

5.1.2.3 Bit Depth and Quantization Error

At the beginning it says the bit depth determines the precision of sample, but HOW? It would be nice to mention that bit depth is actually the memory it takes to store this sample. It is like image resolution; the higher the bit depth is, the less quantization error is, the more accurate the sound is after ADC, meanwhile the more memory it takes to save this sample, giving the readers a general idea of what bit depth is. Also I believe most readers need to recognize the tradeoff between quality and audio file size, but not how bit depth actually works.

The example given on quantized wave explains itself pretty well if standing on itself, away from sampling; and the figures, as well as Max Demo: Bit Depth, also go along with the example (quantization by rounding down). The Flash Tutorial: Quantization, which is made from Audition, however, gives an example of rounding to the nearest integers (for a 4-bit one, it has 15 levels, 7 positive, 0, and 7 negative). I am not sure whether we should keep it consistent through all our examples, or at least mention it somewhere that the example given in the Flash Tutorial rounds to the nearest integers.

The description for Figure 5.7 is just WRONG! I do not see why we subtract the stair-step wave form the true sine wave, since we DO NOT hear the original sound wave, and the unwanted part should be the part which the stair-step wave has but the original wave does not; instead, we need to subtract the sine wave FROM the stair-step Wave, and we will get negative amplitude, which doesn’t matter as long as it is right. OR we can just say the green wave is the difference of those two waves, making it okay to be a positive amplitude.

(Part II coming up...)

June 22- REBOOT!

Today has been awesome.
We finished up most of the Chapter 5 things we need to finish. I need to look over the newest version of section 2 in order to complete my final assessment of the chapter, but other than that I've finished all the other assessments. I have also nearly completed my choral setting of "Day", which I will hopefully complete and perform in one manner or another. The team and I decided, after joking about our skills with reason and sonar, that we would write a pop song. Our song, entitled "REBOOT", is a neo classic dance groove that deals with the ever-present love/hate conflict between man and computer. The whole team contributed to the writing of the lyrics, I came up with the melody and notated it in finale, Erica has started the initial harmony analysis, and we've started a few loops in sonar to use as accompaniment.
Fun as this is, we realized when we started the song that this could be an EXCELLENT form of the final project for this class. If students were asked to create a simple song, create an accompaniment track in sonar or reason, then required to create a music video and mix it down in audition, it would be an all-encompassing project. The hope is that the team and I can get together to make a music video and use all of our knowledge to create a fun final result.

The Research Team presents "Reboot!"

Today we began work on a group song, titled "Reboot!" We came up with the lyrics this morning, and right now I'm working on a drum loop in Reason. We plan to rewire Reason into Sonar so we can combine our Reason tracks with recorded vocals (and possibly a killer saxophone solo via Beth!) After this, we will edit our track in Audition. Updates soon!

June 22nd

Yesterday I promised more comments but didn't follow through. I started to play with vocals on Sonar X1 and I tried harmonizing with myself and came up with a ditty that I liked. Today I worked on coming up with the lyrics for Reboot by the Research team aka the Digital Sound and Music team. I feel like we have some great melody ideas that are ready to be put to the lyrics. I also finished Chapter 5 and started on the evaluations on Sakai.

Feeling Challenged...June 22nd

I came in the lab and was about to start writing about my learning experience from yesterday. Then I just felt it is quite challenging to put my words together since I am not 100% confident that I have understood the material in this chapter. I am also kind of behind on blogging. Hope I can be more productive today. My goal today is to try out the exercises in section 3 while rereading section 1, and try to visualize the process of sampling, dithering and quantization better.

Chapter 5

Chapter 5 is so far the most difficult chapter for me to get through and digest. I've frequently caught myself speed-reading, glancing at the information but failing to retain it... so it's been taking me a while. I think next week will be better, though, when I'm forced to work at a faster pace (I agree with Elizabeth here!)

Also, maybe on Thursday or Friday, could we separate into our pairs, do some work in Reason/Sonar/Finale/Audition, and then present our projects to one another at the end of the day? I think that would make things a little more fun around here :)

June 21

Today we were left to our own devices again. Basically what that means is a bit more chatter, but I've made it through the first two sections of Chapter 5, and should be able to finish the evaluations by the end of this afternoon. This chapter has been challenging, because the material is a little less exciting, but I've found the supplemental materials to be helpful. The florescent lights are starting to bother me, though. I think investing in some lamplight or ensuring we take a brief walk outside every so often would be good for us physically. I'm feeling overtired and am getting persistent headaches and I think the computer screens are to blame. My suggestion for the sake of potential students in this course is that the course materials be printed so that the reading can be done outside or in different locations.

I'm feeling like we're a little beyond the pace expected here. I have read through chapter 5 and taken fairly detailed notes on what I think could be changed. I'm only three evaluations away from being finished with chapter 5. I think outside of the chapters, we really need to have a few goals to be working toward. That way we don't' end up waiting on something else to do. I think that next week when we are expected to fly through two chapters we will feel more productive because we will have more of a time crunch, which truthfully is a good thing for Wake students...

June 21st

I am currently trying to find my way through chapter 5. This chapter is pretty dense I think the tutorials will help condense the material. I am also working on a four section piece in Finale. More comments later!

Chapter 5 Digitalization: Section 5.1.1, 5.1.2 & 5.3.1

After one week of struggling with music theory, finally, here comes the material I couldn’t wait to read about! After skimming through this chapter, this chapter reminds me of a computer science class I took in high school, where I learned about memory computation and different file types, and a math contest problem, through which I got to know decibel as well as comb filtering. This chapter talks about many concepts with comparatively complicated meaning, taking me much time to understand, but compared with those music notations in Chapter 3, these make much more sense to me.

5.1.1 Analog vs. Digital describes the process of analog and digital conversion among and within devices. However, it might be easier to read if the sentences are divided more clearly, say, one sentence for each device. 5.1.2 Digitalization is fairly easy to follow in general. All the concepts are pretty straight forward except 5.1.2.4 and Noise Shaping in 5.1.2.2.5, but I guess it will become clearer after I read the algorithm in section 3. As the material is getting dry when I reached the beginning of 5.1.3 Digital Audio Formats and Transmission, where it starts talking about hardwares, I switched to 5.3, the math and science part. I want to mention that for the readers who are interested in knowing the algorithm behind and are able to read the material in section 3, reading section 2 followed by the corresponding algorithm in section 3 is a very good way to get to know how things actually work.

After reading 5.1.2.3 and 5.1.2.4, I am still very confused by how the sample points are chosen and how the sound waves are quantized. It still makes a lot of sense, but takes effort to think it through. I hope a complete example or demonstration that combines the quantization level and selection of sample points would be given. From my understanding, one sample is chosen after a fixed time slice, and the value is rounded to the lower quantization level. The higher bit depth is, the more quantization levels will be, and thus the closer the shape of the sample points make up is to that of the original sound wave, and the smaller the error wave is… Also I don’t quite understand the concept of SQNR. Does it just mean the bigger n we choose, the bigger SQNR will be, thus the noise will be really quiet comparing with the sound?

Flash Tutorial: Dynamic Range

Clearly states 2 meanings of dynamic range.

I really like the example that compares between Beethoven’s Symphony No. 5 and Deva Premal’s Sammasati. It clearly shows the difference between 2 audio pieces with different dynamic range. On the pages where quantization process is shown (rounding down), it would be nice to show the original position of the sample points, or vertical lines showing where the samples are chosen. I should have written this earlier in the assessment for Flash Tutorial: Sampling and Aliasing. Overall this is very nice learning supplement, and is easier to read than the text.

and read through 5.3.1 Mathematics and Algorithms for Aliasing. I could pretty much tell the algorithm when I was trying out the Flash Tutorial Sampling and Aliasing, but the Nyquist and Aliasing one demonstrates the algorithm much better.

Personal preference:

Can we horizontally line up Figure 5.9 and 5.10 and adjust the table contains Figure 5.11 and 5.12? It just looks quite messed up.

June 20

After what feels like an extremely long weekend, we are back and working our way through Chapter 5. In all honesty, this chapter is a little tough for me to get through, as it is full of math and equations, and is a rough jump from the very comfortable chapter 3 material. In order to not get bored, I've been working through my setting of "Day". It might seem like a bit of a suck-up move, but honestly I've become much more fluent with Finale after working on a composition, and certainly have some ideas on how to incorporate my work with the other software programs we're using. What I'd like to figure out is how to comfortably record my finale work into an MP3 in order to save the track and work on the composition later. I'd also love to print.... do we have a printer around?

5.1 sections

5.1.1 - Analog vs. Digital

This is an easy to understand section. The content makes sense and sets up the important concepts for the rest of the chapter.

5.1.2.1 - Two Steps: Sampling and Quantization

I find it annoying that a term (Hertz) can be used with different meanings, but I know nothing can be done about that here. I found sampling and quantization to be relatively straight forward. If the difference between continuous and discrete is understood, I feel like sampling and quantization will make sense to the student.

5.1.2.2 - Sampling and Aliasing

I thought this section was easy to understand as well. The computer must select points to sample, and enough points must be sampled to create a decently accurate digitized version of the track. This requires the use of the Nyquist Theorem, or else the sample won't be accurate enough. I think it is pretty straight-forward.

Error on page 5. It says "The value of these high sampling rates will be discussed in section 4.2." Since this is in chapter 5, it should say "The value of these high sampling rates were discussed in 4.2."

5.1.2.3 - Bit Depth and Quantization Error

If you want the music majors to really understand binary, there needs to be a good lecture on binary. Elizabeth was still confused about it after reading, so I tried to explain it to her (hopefully my awful teaching made enough sense to make binary a little more clear). Once you understand it binary is pretty easy, but it takes a bit of work to learn it. Bit depth is a little confusing, but I feel like the supplements do a pretty decent job explaining it. Assuming this is what actually happens, figure 5.6 also clears this concept up by showing the positive and negative values for the bit depth. The reason that quantization occurs also makes a lot of sense, especially with the help of the different related figures.

5.1.2.4 - Dynamic Range

I'm not a big fan of this section. It gets a bit dry after a while, and after reading a few times, I'm still not sure if I fully understand what dynamic range is in this context. A lecture on this might help, but the text and supplement standing by themselves don't give a great explanation of the concept.

There is another error here at the end of the section on page 12. It again says "will be further discussed in chapter 4."

5.1.2.5 - Audio Dithering and Noise Shaping

Audio dithering is simple enough, but noise-shaping is a little bit confusing. I feel like a visual representation of this would be beneficial.

5.1.3.1 - Audio Data Streams and Transmission Protocols

Discussions of the different accessories required for sound production like this section can be a bit boring sometimes. This section clearly explains what the S/PDIF does and the better qualities of the AES3, but I don't really have much more to say about this section.

There is a typo at the top of page 15. The second "meters" is spelled "meteres."

5.1.3.2 - Signal Path in a Audio Recording System

The discussion of buffer size in this section is interesting and quite relevant. It is helpful to understand why the sound cuts out every once in a while. Many of the computer science majors will probably already know this information, but a clear explanation of what is happening is quite helpful and the music majors probably don't know this info. It is also very practical to what is going on in the class. Selecting the right buffer and sampling size to create the best sound capturing is crucial to successful digital music creation.

5.1.3.3 - Digital Audio File Types

This was an interesting section, I thought. I've always been curious about what the actual difference is between the different music file formats. I found the discussion of compression to be interesting and informative. It was easy to understand and fun to learn about. Even though compression makes sense and the reasons that data can be lost during the process are easy to understand, I also though the supplement helped with understanding even more. I thought it was a pretty good supplement.

On page 19, a little bit of the bottom of the aside is covering some of the text. It is just the very top of a few letters, but I'm sure it would be pretty easy to fix.

Chapter 3 Musical Sound: Section 3.1.6 - 3.2

This is the last day of this week, and I finally finished up Chapter 3. I have to admit that it takes time to digest the material covered, but what is more challenging to me is to grow a good sense of music.

First I want to appreciate Elizabeth and Erica’s help in the last two days. Music notation does seem intimidating to me. I had a hard time absorbing the information, and had to reread the same sentence again and again to understand. I think both of the music students had experience in teaching/tutoring music theory, and they demonstrated and explained the basic concepts very well. I do hope this kind of collaboration will occur more during the rest of the project. While I was evaluating the learning supplements yesterday, Elizabeth helped me with understanding concept of chords and inversion, as well as familiarizing with the notes with accidentals that each key signature represents. With their help, I reread 3.1.6 Musical Composition more thoroughly, and understand the basic principle of musical composition. Today when I start playing with Finale, I feel much more confident than a week ago, at least I have a sense of what I am doing now.

I would say 3.1.6 and 3.2.1 are the most successfully written part of this chapter (3.2.1 is the only subsection in 3.2; why don’t we just have 3.2 instead?). Section 3.1.6 gives detailed information on each topic, while 3.2 lets us have a little bit taste of everything. With the music students’ help, I am much clearer with the concept of different kinds of intervals, and how they affect the naming and effect of chords. Section 3.2.1 introduces the reader different expression of music notes. I found the various formats are quite interesting, especially the event list. It is very compsci-ish, easy to be seen as a database that each element can be fetched and edited easily. I am very looking forward to going through the chapter on digitalization, and hopefully get to know exactly how digital sounds are made and stored.

Software-wise, I found looping in Audition comes very handy. Audition is the software that makes the most sense to me so far (-___ - …struggling…). The interface is very user friendly. It is fairly easy to just pull in a piece of sample and edit it. The only problem is when I was exiting Audition my computer froze for 5 minutes and muted. Finale would be very helpful to the ones who can compose. I just tried to type in Twinkle Twinkle Little Star, saved, and reloaded it, making sure it works on my computer. Hope I will finish the reading earlier next week, so I will have more time playing with the softwares.

I did not try out the section on science, math, and algorithm this time. The MATLAB one seems of not much value to work on. But the Max one appears very appealing. I might try it on leisure time later.

Finale Work June 17

Today I spent a lot of my time creating musical ideas to use with the synthesized instruments we will create later in the course. First I began by composing a piece entirely of my own, accompanied by piano (perhaps eventually guitar), and notating that in Finale. Then I thought it would be interesting to use one of Dr. Burg's poems, Day, to create a choral setting that could be used in tandem with synthesized accompaniment. I figured the music students and I could sing each part (I'm hoping to compose an SATB version, but this could easily be altered into a SSAA version), and we could overlap them to create the necessary harmonies. This would be a very cohesive project, incorporating a lot of different musical ideas and lyrical concepts.

June 17th

I started the day looking at the chapter three layout I compared it to the chapter outlines on the gmusictheory.org and I agree with Elizabeth's alternative for the chapter. I just think as music students we are used to learning theory in a certain way, but for first time students the current format may not be a problem. I think what could cause confusion in the classroom are the multiple ways one can learn how to perform various theory exercises for instance "naming the major key". I feel as though little known short-cuts will cause classmates learn from eachother. Eric helped me so much today he fixed the problems I was having with Finale and helped me figure out Sonar X1 Producer. I actually find this version to be more user friendly. I watched a youtube video on Audition to get more familiar with it, although my computer does not have Audition as of right now. I touched base with Erin and we decided to compose and record short ditties that we will later share...

Chapter 3: 3.1.6.3 -

I finished up Chapter 3 today, so here is the rest of my review of the chapter.

3.1.6.3 - Chords

I've always wanted to know more about chords, so I found this section to be fun and interesting.

The info in this section is kinda confusing just reading it from the text, but with the mini lecture the girls gave on Wednesday and with the help of the supplements I think I have a decent understanding of the different chords and could identify them with decent accuracy. To get any better, I would just need to practice it more.

Flash Supplement - Chords

This is a good supplement. I t is fun and I didn't notice any problems with it. It is challenging for a beginner, and does a good job of teaching the concept. I think that the way this one is designed is more effective than the game style supplements earlier in the chapter ("Beats in a Measure" and "Key Signatures"). I get to spend the amount of time I want to spend selecting what I think is the best option. The other supplements were fun, but I don't think they taught the material as well.

3.1.6.4 - Chord Progression

There isn't really much to say about this section. Tonality and cadence was interesting to read about. After reading this you can understand better why a lot of music sounds the same, just placed at a different tempo and rhythm.

The two supplemental videos here are not on the supplement page on the website.

3.2 Applications

I thought it would be better to just keep all of 3.2 together since it is all so similar. I found it interesting to know exactly what the different abstractions of the staff actually meant. I see tabs and chord progressions everywhere, so it was fun to actually learn exactly what was going on in those music sheets.

Max Demo - Music improvisation demo

This was kinda fun and does what it is expected to do well. No suggestions or criticisms of it.



Chapter 3 Conclusions

This chapter required a decent amount of collaboration between the music majors and non-music majors. It was fun to get to learn more from them and helped us become more comfortable talking to each other. I think that a lot of the concepts in this chapter require an accompanying lecture to make sense for beginners. The supplements were decent, but I think the 2 game supplements (Beats in a Measure and Key Signatures) would be better if they were designed more like the 2 supplements in the chords section.

I agree with the music majors that the order of this chapter is a bit off. It seemed like the revised order that they gave would work, and I'm sure they know what order would make the most sense.

I had fun learning more about MAX from Eric. There is a lot to that program and it was much easier to find things when someone who knew what they were doing was there to help out.


This is a bit unrelated, but I thought it was worth mentioning somewhere. For the class, I think that it would be a good idea to make sure that there is a good mix of music and cs majors all throughout the room. It would be detrimental to the learning experience, I think, if the different majors group together and don't associate with each other at the beginning. I think that having majors mixed everywhere so that they can explain things to the cs majors if they get confused about music things, and cs majors to help music majors if they get confused about cs things, is an important part of the interdisciplinary aspect of this class.

No Rhythmic Supplements in Ch. 3

Elizabeth just raised an excellent point- there are no rhythmic exercises in Chapter 3. When students are learning how to read music, there is always some form of activity pertaining to clapping a beat or rhythm. I wonder if this would be something done in class? We should discuss how to incorporate rhythmic exercises into Chapter 3 sometime soon.

June 16

Today I went over chapter 3. From my perspective the material is pretty much standard, but I can't imagine fully understanding the circle of fifths using the explanations given. The explanations along with an instructor and a lot of other exercises would need to be implemented in order to completley grasp the concept. When I took a music reading class we spent two class periods on the diagram. I think that supplementary activities are needed with chap 3. I find gmusictheory.org and musictheory.net very helpful resources. The tutorials and quizzes are very useful and applicable to all the concepts in chapter 3. I think the note values should start with the whole note and it would be easier to read if they are all on one page. I have seen this displayed in a tree format with note values and I think that format could be useful for this chapter. The way the major and minor scales were explained was perfect. I liked the chart and I think that is the easiest way to learn that. The interval section is nice if used as a refresher, although I am not sure how long it would take a non-musican to grasp that section.
Percy and I also talked about the final project and what kind of sound we are going for. Percy suggested a salsa rhythm and we recorded it. I suggested we add a big band sound along with a melodic chorus all of which we will decide with Erin.

More June 16

Despite some difficulties in understanding the tutorials, everyone seems to be doing well. I might still have a few evaluations to finish after lunch, but most of chapter 3 is finished. What I'm really enjoying is getting to answer musical questions from the rest of the team. It's great to have the compsci students here to fix my sound and tell me how to switch out my keyboard, so it feels good to be able to answer their questions about music. In many cases though, I think the confusion on the tutorials is more a product of a confusing setup than their "novice" status when it comes to music reading.

June 16

Today we have all the necessary evaluations on Sakai, so we are able to start the day by completing those. My goal is to have them finished by lunchtime, so that I can start working with audition to try to get closer to being able to create loops and grooves. I'd like to see if I can work with the rest of the team to learn how to do that, because after a morning of very quiet work on Sakai, it would be nice to collaborate.

Also I'm becoming increasingly frustrated with my computer and all its workings. I find that my sound cuts in and out, my speakers are glitchy, my MIDI keyboard wire was not working well, and Finale continues to freeze up my computer. I suggest for this course that some real time be devoted to making sure that all the hardware is completely functional, because I've spent a lot more time rebooting my computer than I have learning about the software the way I'd like to. I also wonder if the course is best taught on PCs, as mac is becoming more and more standard for creative endeavors such as music editing.

Week 1

June 8th, 2011
The first day of the project was a bit overwhelming... I came in and was lectured on pitch, frequency and sound waves in unfamiliar softwares Reason and Sonar. My team was thrown into Reason, Sonar and a lot of technical difficulties. I remember being frustrated that the keyboard wasn't registering in Sonar and the sound were not working only to find out the speakers were not properly connected. It was challenging to learn all of the settings for Reason and Sonar because we were learning so quickly in order to catch up to the full-time students. I personally felt that the settings were not hard-fast rules. I felt like even if I remembered how to set everything up technology was not on my side. The truth of the matter is the first day was all trial and error. I left the lab enthusiastic for the next day to be easier.
June 9th
Today I worked alone and took cues from Erica and Elizabeth and watched youtube videos on Sonar. I also prepared for Friday's group session. Jordan helped me setup Sonar with Reason and I wrote down all the settings and sent it out to Erin and Percy to ensure that we didn't waste group time.
June 10th
The biggest feat was made when Erin and I recorded a track using vocals and keyboard. Erin came up with a melody and I sang on vowels. Our recording is very short and I fell flat, but I was happy we put something down. We asked Percy to listen to it and he thought that it was a step in the right direction to reach out final project. I am so proud of the team and how seamlessly we work together, although working with technology can be frustrating at times we feed off of each other and learn new things. Erin and I looked into Finale and we learned we can play our song into Finale. We had to learn this the hard way when we had Sonar and Finale up at the same time and Finale was playing a delayed playback of our piece this was very confusing but Dr. Burg cleared things up for us. Jason came in and talked to us about the pre-sets on Reason and how to make a drum beat. This was interesting and I learned about the things in a synthesizer. All in all the first week was not bad at all I learned a lot and can't wait to compose the final project.

Complete Chapter 3 Evaluation

This evaluation follows the format of the sakai forms, but many sections exceed 4000 characters. This is the complete version:

What practical skills were helped?

Table 3.12: Ratio of Beginning and Ending Frequencies in Intervals
This chart is very interesting, and it shows us the mathematical ratios behind what we consider to be "consonant" and "dissonant". I find the harmonic intervals to be very useful, because it helps us to understand the development of keyboard instruments and tuning. This information will help me understand how my tuners work, and also allow me to account for temperament in my digital music.

What concepts were well explained?

I found the technical definition in terms of frequency of how tone and timbre are created was very helpful, and written from an interesting perspective apart from my own. I did find one error, in the section dealing with overtones, in which percussion instruments are said to not have harmonic overtones. This is not entirely accurate, as many percussion instruments are pitched.

3.1.2 Tones and Notes
I did think that in this section the math associated with half steps on a keyboard was extremely interesting. Since this is something I use each and every day in my area, I liked understanding the basic underlying math that describes a chromatic scale.

The text also discusses the idea of consonance and dissonance. Saying that Western music is based upon consonance isn't completely fair- the middle ages were based much more on dissonance than consonance- but the explanation of tension and release is well said.
I found table 3.9 to be very helpful- this is a very useful tool for anyone working with chord progressions. The same is true of figure 3.35- both images are quite useful and well-laid out.

3.1.6.4 Chord Progressions
Using the Twinkle Twinkle melody to demonstrate chord progressions is useful- it would be good for students to try to play the melody on the piano. Using the supplements to play these progressions so students can hear the accompaniments is helpful in this section. I also really liked the section on cadences. I thought the information was clear, accurate, and concise, and made them fairly easy to identify theoretically and aurally. I think that the fact that Mozart wrote this melody should have been mentioned earlier, and I also think that if the text is going to call it a variation, it should define a Theme and Variation form.

*Engaging and interesting?

Reorganization?

The frequency relationship defined as an octave is a definition that will confuse your music students. While discovering the relationship between frequencies is interesting, I think that in order to start defining intervals, you should define whole and half steps first. An octave, by musical definition, is 8 notes of the scale, or 12 half steps. Also, when introducing sharps and flats, I wouldn't wait to explain that C-sharp raises the pitch a half step, and that a flat lowers the pitch. It might be that the whole section on accidentals belongs BEFORE the mention of any intervals- including the octave- because intervals are defined by whole and half steps (letter names are only one way to define intervals). That way enharmonics could be explained here as well.

3.1.2 Tones and Notes
Showing a piano keyboard without describing that each note has a corresponding key may not be helpful- I think this section should be reworked in terms of order.

3.2.1.5 Guitar Chord Grid
I don't understand why we are spending so much time dealing with guitar tab and other types of notation for guitar. Is the idea to be fairly standard with keyboard and guitar as the primary instruments for learning? Other musicians might find this frustrating, so I want to know exactly why the focus is on guitar.

3.3.2 Equal Tempered vs. Just Tempered Intervals
If the text is going to mention Temperament, it is imperative that Bach be mentioned at some point, as he was the first to write in all 12 keys for the "well-tempered clavier (keyboard instrument)." With that addition, I found this section to be REALLY cool- I've always wanted to better understand the math behind temperament, and it really helps with the understanding of tuning and keys to know how the frequencies behind it work. I also think that Table 3.11: Frequencies of Notes from C4 to C5 is very useful for digital media, because it would help musicians use the programs available to them more efficiently by knowing both the pitches they need and the frequencies necessary to make them.

Better job relating concepts, practice, science?

3.1.1 Context
I begin this section with a certain amount of trepidation as I hold a bachelor's in music performance, and am going into the field of music education. As such, I not only have high standards for the level of accuracy of music theory and history, but I also have high standards for how well it is presented to potential non-musicians.

First of all, the introduction of context is somewhat misleading. Western music tradition began long before Mozart, and started essentially with the development of Gregorian chant. Also, MOzart and Beethoven were part of two distinct musical eras, so it would be better perhaps to mention Bach instead. Secondly, considering Gregorian chant to be somehow different from Western music isn't exactly fair, as chant used church modes which are the foundation for the diatonic system we use today.

Table 3.10 is bulky- the columns that say "chord type if the triad sequence comes from a major key" could be switched to say "major" or "minor".

What could be added?

In the section describing accidentals, it would help to add that accidentals raise or lower a note when it needs to be different from the key. That way the later section on keys would make more sense- now I think people would find it confusing... why have a key signature if you can just write accidentals (or vice versa)? Simply clarifying early might help clear that up.

When explaining the treble and bass clefs, it would be helpful to include that the treble clef covers a higher range of notes on its staff than does the bass clef. This would explain the difference and why one is on top of the other.

3.1.5.2 Notes and Their Duration
Table 3.3 doesn't make the most sense when trying to explain note duration. The best way is to break down things from the whole note down. This way, the relationship from one note to another is made clear from the longest duration down. A similar format would work for explaining dotted notes, with a dotted quarter note creating a set of three half notes (or one quarter and a half note) etc.

In figure 3.17, adding lyrics to Twinkle Twinkle would not only help with practicing reading pitches, but also will help students place each note value of the tune with a written note value. It is also unnecessary to say that this is the "right hand"- it's just the melody, and is technically composed by Mozart as a theme and variations.

3.1.5.4 Rests and their Duration
Table 3.5 has the same problem that the note duration had- if you began with a whole rest and worked DOWNWARD in the format of the chart above, the rests would be much clearer. It would also be helpful to show rests next to their corresponding note value- that way students would be able to more easily connect that a quarter note is the same value as a quarter rest, etc. Table 3.6 is fairly clear, but I still feel that there is room for practice. Rhythmic notation is crucial, so maybe if each student was given a note and asked how many 8th, 16th, or 32nd notes it is equivalent to, including dotted notes, they would be able to more easily understand that it is fairly simple math, and not something to be feared.

3.1.5.5.1 Key Signature

I would prefer that in this section the use of 2's and 1's be altered, but generally within this structure the meaning is fairly clear. Perhaps have students create scales by starting on one pitch and creating the 2212221 pattern. Then identify the sharps and flats necessary for each scale. It would also be helpful to mention the idea of "flat keys" and "sharp keys" so that students understand that a key signature contains ONLY sharps or flats.
When discussing a key signature, you MUST mention what this tells a performer. If I am reading a piece in the key of D-Major, the key signature tells me that throughout the piece, unless there is an accidental, I have to play F# and C#.

3.1.5.5.2 The Circle of Fifths
When discussing the circle of fifths, it is useful to show a piano image. This makes the "counting up" or "counting down" process much simpler, because students are able to visualize how many half steps they're moving. The idea of adding or subtracting sharps and flats is pretty good- but it might be hard for students to understand that you are actually adding sharps clockwise all the way around the circle, and adding flats counterclockwise. This is easy to see when on one half of a circle (all flats or all sharps), but this is much more difficult to understand when you make the switch from sharps to flats (or vice versa) at the bottom of the circle. This may take some explanation on the part of the professor- but should be gathered given what sharps and flats do.

I think the most important part of this chapter is providing basic reading skills and also allowing students to make the connection between written notation and what they hear. The more listening exercises you can include, the more comfortable non-musicians will become with the idea that notation is just a way of writing what they've been hearing for years.
Figure 3.26 would benefit from having the names of the intervals written beneath the notation- that way students don't have to count them or read for them in the paragraph- you will be able to see the interval written right below the interval notated. The same should be true of 3.27.
When I got to the explanation of not being able to make Perfect intervals minor, I realized that there hadn't yet been a clear definition of what makes a perfect interval different. I think this information needs to be given at the beginning of the section on intervals. A perfect interval is so named for its high levels of consonance, and also because its inversion is also perfect. The point about the high levels of consonance would be useful to mention for the purpose of the later section dealing with frequency and consonance.
Also- Form is entirely left out of this section. I'm not suggesting that we cover Sonata-Allegro form and discuss transpositions from the tonic to the dominant when composing a fugue... but I think some mention of how repeat, da capo, coda, segno, and 1st and 2nd ending signs work would be useful.

Anything not relevant or helpful?

On page 3, define the term "chromatic" as referencing notes that are a half step away from each other. Also, the term "semitone" is typically used in European English, and not generally heard in the US. While it is technically accurate, the "half-step" is a much more commonly used term. The same is true of "whole tones"- generally the accepted term is "whole step".

3.1.3 Music Versus Noise
Careful with the idea that music is easily distinguishable as noise. Your lovers of 20th century experimental music will take issue with that, so you might want to be prepared to defend Western traditions. Many very well trained musicians experimented with very unpleasant sounds in recent decades, and their pieces are still completely justified musical endeavors.

Once again, be careful with generalizing all percussion as being non-pitched. Many percussion instruments are, and your timpani players will be offended. They ARE transient, but wind instruments can create very percussive sounds as well.

3.1.4 Scales
Very rarely does anyone refer to types of scales as intonations. Generally your scales are called diatonic or they aren't, so this term isn't particularly useful. Also, the system of writing the scales as a series of 1's or 2's is extraordinarily uncommon and confusing. You are way more likely to hear musicians talking about scales in terms of whole and half steps, or abbreviating half steps as ^ and whole steps as arcs or upside down half-squares. You would be better off to show these scales on a keyboard or defining them as patterns of "whole" and "half"- this would be much clearer (even to math students, I believe, because the patters are easier to see than a whirlwind of 1s and 2s) than numbers.
Also in this section, it says that there are two types of diatonic scales. Be sure your students understand that there are two TYPES, not just two diatonic scales (of which there are 84). It is also important to know that there are other "major" scales (the other church modes) that are not in the 2212221 pattern. In addition, the "familiar" [do, re, mi, fa, sol, la, ti, do]: "Sol" has an l at the end in traditional solfège syllables (which is what these syllables are called in musical pedagogy).
In table 3.1 the vii is called the leading "note", which is more commonly referred to as the leading "tone". The section following regarding minor scales is completely unhelpful. The best way to learn minor scales is to HEAR them, and see what's being played on a keyboard. You need a visual here, with pitch names, a staff, and the ability to HEAR each different kind of minor scale. Most people will be able to tell that there is a difference, and the text will explain WHY they sounds different. While using a musical example is a good idea, Showboat won't be particularly well known for students now, and is a touch controversial, so perhaps another well known piece could show a minor key- think God Rest ye Merry Gentlemen, maybe. Again, the 1s and 2s (and now 3s) are very confusing, and table 3.2 is a wash of numbers and patterns that are hard to distinguish. How necessary is it to know some of this? How will the combination of whole and half steps creating scales (as opposed to just knowing the pitch names that are used in each scale) help students create digital media? I think most students will be wondering why this is included, and what good it will do them.

3.1.5.1 Score
The paragraph below figure 3.10 includes a sentence about whole notes shown in the table below- this is irrelevant, and will only confuse the students. They can figure out that the notes below are notes, and once you describe note duration, that will be explained without the disjointed introduction.

3.1.5.3 Rhythm, Tempo, and Meter
Rather than saying "placement of accents" in notes- perhaps change it to "emphasis", as accents are something distinct and having to do with articulation.
The explanation of time signature in this section is way more confusing than it needs to be. While I understand the idea of creating an "equation" of sorts, it would be better to set it up as an explanation rather than as variable. For example: # of beats per measure/what kind of note gets the beat. The top shows HOW MANY of the bottom note are in each measure. It would also be much clearer if there were a visual example of a measure included at the mention of a measure (this way students will be able to tell why it is also called a "bar").

3.1.5.5 Keys
On page 16, (and tables 3.7 and 3.8) the discussion of how to determine the tonic from a key signature is MUCH harder than it needs to be. Finding sharp keys is done fairly well, but the easiest way to find a flat key is to look at the second to last flat in the key signature. If there are two flats, B-flat and E-Flat, the key is B-Flat. This works for all flat keys with the exception of F-major/D-minor, which only has one flat. If you can remember that ONE flat key, the rest of them are quite easy to find. There's no need to count down 5 half steps. Finding the minor key just requires going down a minor third from the major key (or three semitones in this context).
After reading this section I'm not wholly convinced that compound intervals are worth so much time- I think it would suffice to say that intervals bigger than an octave exist, and that you can essentially pull one of the pitches closer to the other by an octave to determine the compound interval.
3.1.6.3 Chords
I think the explanation for the minor triad is overcomplicated. The best way to explain chords other than major chords is to start with a major chord and alter it. For example: start with a major triad, flat the third, and you have a minor triad. If you start with major and flat the third and fifth, you have diminished, and if you start with a major tried and sharp the fifth you have an augmented triad. I find this explanation in relation to the major triad to be much easier to understand.
Trying to combine Twinkle Twinkle with Over the Rainbow isn't useful. The progression, flatly, isn't the same. The second chord really should be a IV for the progression to work. Is that what the text means by sounding a bit "off"? That is very unclear. There are plenty of other pieces with the same chord progressions. Try youtube remixes, (my favorite, http://www.youtube.com/watch?v=JdxkVQy7QLM). The progression I IV V I IV I V I is very common, and works for a number of folk songs such as This Land is Your Land, etc. Maybe this progression would be better to exemplify the flexibility of progressions.

Mistakes? Typos?

3.1.5 Musical Notation
3.1.5.1 Score
Page 9, 10- "There are scores of different types, depending on the instrument being played", SHOULD READ: instrument(s). Also the plural of staff in the next paragraph can also be "staves", but both are technically correct.

Firgure 3.18 has a few issues. First of all, it should be labeled as Mozart's Eine Kleine Nachtmusik. Also, this piece is NOT written in 6/8 time. The original version (and the most widely accepted transcriptions) was written in 4/4. Writing it in 6/8 creates groupings of notes that don't make sense given the melodic shape. The same is true of Tutorial 2.1.5.4: Music With Rests. Though it is true that the eight notes line up similarly, 6/8 time groups notes in triples, which isn't conducive to the structure of the melody. It is also written in such a key that you end up with a lot of ledger lines above the staff. Either take this melody down an octave or write it in a friendlier key so that more notes lie on the staff. It will be easier for students to identify the pitches that way.

Key Signatures:
To say that keys are no different except their higher or lower pitch is not entirely accurate. If that were true, we would all play in C major or A minor all the time unless we were dealing with singers. Composers write in certain keys because of varying tone colors- flat keys are often a smoother, darker sound while sharp keys tend to be brighter and more pronounced.

3.1.6 Musical Composition
3.1.6.1 Historical Context
Polyphony became more standardized in the Baroque period, but was most certainly used in the middle ages. It began primarily with decorations on Gregorian Chant, and developed into organum. Be sure not to say that polyphony wasn't used until the Baroque, because that is inaccurate.

3.1.6.2 Intervals
In the introduction to this section, the text reads "An understanding... composition begins intervals". It should read "begins with intervals".
On page 24, the text says that sharps or flats aren't significant when naming intervals. This is incorrect- F and D is a sixth, F and D# is an augmented sixth; they do not sound the same, so they are not named the same. This is explained in a later section, so it's better to just leave those sentences out and explain augmented intervals later.
On the figure 3.28, an octave is listed as a "perfect eighth". This is a term that isn't used in musical circles, so it would be better to call these intervals a perfect/diminished/augmented octave. This chart is labeled as "all intervals"- it should rather say "all intervals within the octave".
Page 26 says "compound augmented fifth", which should, according to the example, say compound augmented third.
Figure 3.34 is the wrong figure. According to the title it should be dominant 7th chords in 3 inversions. It would also be much easier to abbreviate the intervals:
M2 (Major second), m2 (minor second), P4 (Perfect fourth), P5 (Perfect fifth), do7 (diminished seventh), A+6 (augmented sixth), etc. This might help clean up the layout of some of the charts.
The lyrics to Over the Rainbow are incorrect. ... "way up high, There's a land that I've dreamed of... once in a lullaby".
3.2.1.3 Tablature
pg. 34 says that tablature uses "six lines like the regular musical staff". This is wrong- regular staff has 5 lines, not 6.

Chapter 3 Musical Sound: Section 3.1.5

3.1.5 Musical Notation

I do not have much constructive to say about this section. I will just express some personal opinions on how to let one learn music better. First, I would like to preview an example of all the musical notations that we will talk about this section at the very beginning as a whole picture.

3.1.5.1 Score

When talking about the mnemonics, I want to see a figure showing each of them next to this paragraph so I don’t have to flip back to last page, plus the figure on page 10 does not group notes by their positions.

3.1.5.2 Notes and their Duration

This section is fairly short, and the material covered is very easy. As it says “each time we add a flag, we divided the duration of the previously defined not by 2”, why don’t we reorder the table, going from whole note and “add” flags on later. Or maybe a figure showing the time length horizontally instead a table taking 2 pages could show the relations better.

3.1.5.3 Rhythm, Tempo, and Meter

This part is quite straight forward. Do we really need to know those Italian key words.

3.1.5.4 Rests and their Duration

Also, a table goes from the longest rest to the shortest or a figure showing the time length horizontally might be better.

- The Video Tutorial: Music with Rests does not exist

- If it does, it should go with this section, but it looks like going with the next one.

3.1.5.5 Keys

3.1.5.5.1 Key Signature

The key signature is easy to see and but, again, hard to know well in short term.

3.1.5.5.2 The Circle of Fifths

The circle of fifths is absolutely helpful, however, if we could talk about intervals first the word “fifth” would make more sense.

3.1.6 3.1.6 Musical Composition

I was at first having trouble reading and moving on at this part, but after Elizabeth and Erica’s explanation, most concepts are clear now. It’s just a lot of minor questions here or there. Memorizing all these terminologies shortly is quite challenging. But on the whole this section is much more organized than some previous ones.

Overall 3.1 explains the music ideas in a more science way, which pretty much works for me.

June 15 part 2

The team and I were amazed at our collaborative efforts today to reorganize and, essentially, teach Chapter 3 to each other. Before lunch we got ourselves caught up in terms of blogging and filling out Sakai evaluations, and as we finished we worked with the software to see if we could make loops on Audition. I didn't feel like I made too much progress there- I'll need to work with more users manuals to feel comfortable with that material. After lunch, the whole team tackled chapter 3, and we taught all of the material up to rhythmic notation. We looked at the chapters table of contents and altered the order of things a little, and taught the other members of the team how the basics of music function. When we finished as much as we could handle, I spent the last hour of the day working on recording some things in Sonar- and doing a LOT of troubleshooting with my midi keyboard. We determined that the keyboard itself was struggling, and switched it out, so now I have a consistently working keyboard. I used that to continue my songwriting, which took me up to the end of the day.

Collaboration Time!

Today Elizabeth and I plan on reviewing musical notation with everybody. We are currently at work on a lesson plan based on the information in Chapter 3. Will update later with details!

June 15

Today I began without much direction. I have two mp3 files fairly close to completion, and the beginnings of a song that I would love to notate in finale. I have several problems: The main issue is that my computer simply refuses to hear my midi keyboard. It would be much easier to key in my melody and experiment with chords if I had a keyboard that worked. Also, finale freezes regularly. I think my computer has too much going on, and it really can't handle it all. So if I can't use finale, and I can't get sonar/audition/reason to hear my keyboard, and I've finished chapter 3, and there are no evaluations on Sakai.... what EXACTLY should I be doing?
I've started on more users manuals, and I'm checking out a few tutorials online, but I'm afraid that I won't maintain a great deal of information if I'm not doing the tutorials along with watching them. I'm going to employ the use of some of the other Computer Science students after lunch to see if I can make any progress. I'm fairly solidly frustrated by the entire morning's progress.
If I can't get my computer to work for me, I will spend the afternoon reviewing my chapter 3 comments and talking them over with Erica. We're going to try to see what reorganization ideas we have, and see if we can explain some of these concepts more simply. Then I'll go through all the chapter 3 tutorials again and clean up my responses- I should only have to copy and paste once the evaluations are posted on Sakai.

Chapter 3 Sections 3.1- 3.1.6.2

Forgot to post the last few days, so I just included everything in this post. Kinda long...

This chapter should be interesting, since I don't know that much about music. I feel like it may be a bit intimidating, but i think it will be fun and I will learn a lot. I have a basic understanding of music already, but I think that I will understand it much better after this chapter.

Section 3.1 - Context

This section gives a basic introduction to some of the concepts and some music history that will be studied in this chapter.

Section 3.1.2 - Tones and Notes

This section focuses on defining several of the different musical terms and concepts that will be discussed later, such as tone, note, overtone, octave, sharp, flat, major, minor, etc. I knew much of the information, but learned a few new things here. I was a little bit confused as to why there are both flats and sharps and I was hoping there would be some sort of an explanation for that somewhere in the text, but I couldn't find it in the text. Fortunately, Elizabeth was in the room when I was curious and she explained this concept in greater detail. I think adding a little more explanation of why we use both flats and sharps would be better, instead of just saying that any semitone to the left is a flat and semitone to the right is sharp. To a non-music major, I've always been curious about that.

Other than that, the rest of this section is pretty straight-forward.

Section 3.1.3 - Music Versus Noise

I thought this was an interesting section. Reading about the science of why we find certain type of music to be more appealing than others is something I find fascinating and enjoy reading about. I could read a book about that just for fun, so this section was fun for me. Also, the discussion on the ADSR and the amplitude envelope was interesting.

3.1.4 - Scales

There were several interesting concepts in this section, and learning about the different types of scales was kind of fun. I know that the music majors were annoyed about the use of 1 and 2 instead of whole-tone and semi-tone, but I didn't have any trouble understanding it. On the other hand, using whole-note and half-note would be easy to understand as well and would annoy music majors less. Since the CS students don't know any other way of doing this, most likely, it wouldn't hurt them to use whole-/semi-tone instead of numbers and all of the music majors are probably going to find this annoying. Because of this, I would probably go ahead and change the usage of 1 and 2 to whole- and semi-tone.


3.1.5.1 - 3.1.5.4

I already knew all of this content, so it wasn't difficult to understand. I think it was written well and I didn't notice anything that needed to be changed.

Max Demo - Recognizing Notes

This is a pretty fun supplement. It is helpful and entertaining. It works decently, but the score does not work, and it will just accept whatever answer you give it. definitely needs to be worked on. It also says that it is from Chapter 2

Flash Supplement - Beats in a Measure

This was a fun game. It does a good job of testing knowledge of time signature. There should be a level at the beginning where there is no time limit. Also, there should be an option at the end of each level to retry or to go to the next level.

3.1.5.5.1 - Key Signature

Honestly, as a computer science major with little musical experience, this section is dense, long, confusing and frustrating. While I have been fairly interested in most of the other music related sections in the book so far, I simply couldn't maintain concentration while reading this section. I think I understand it after reading through a few times, but I'm still pretty confused about it. I think with a lecture this would be better. Perhaps some worksheets for practice would be beneficial as well.

Flash Supplement - Key Signatures

This was kinda fun, but it moved really fast for a beginner. Even the early levels were too fast. I'll say the same thing about this supplement that I said about the Beats in a Measure supplement. I think it would be good to have a level at the beginning that allows you to choose the correct signature without having the time limit. That would make it less stressful and beginners would probably like it better. Also, if the student fails a level, they should have to redo it until they are successful. Ideally, at the end of each level there should be a button for retry and a button for next level.

At the bottom of the screen where it says which chapter and section the supplement is from, there is an alignment error.

3.1.5.5.2 - Circle of Fifths

The opening line to this section is awkward. Since this is still part of Section 3.1.5, it should say something like "In Section 3.1.5, we have been showing how keys are distinguished by the sharps and flats they contain," or whatever the proper grammar is there. Past tense doesn't work there.

Since I was not entirely comfortable with key signatures, I was a little confused by this section still, but I understand the concept of the section. If key signature is understood, then the Circle of Fifths doesn't seem too difficult to understand.

Flash Supplement - Circle of Fifths

This supplement doesn't add anything to the learning process and everything found in it is explained well in the text. I really don't think it is necessary.

3.1.5.5.3 - Key Transposition

This is pretty simple and easy to understand.

Flash Supplement - Transposing Keys

This is a good supplement. It is simple and easy to understand, but ensures that the student has a good understanding of the concept and does a good job testing them.

3.1.6.1 - Historical Context

In the first line of the first paragraph, where it says BC, there is a random period ("BC. the Greek..."). Either there should be one after the B as well, or there shouldn't be any period there.

While interesting, this section sort of seems like it is just randomly thrown in there. I don't have any problem with it, but it doesn't seem like it adds all that much.

3.1.6.2 - Intervals

"An understanding of melody and harmony in Western music composition begins intervals." This sentence needs to have "with" added before interval. It is the first sentence in the section. In the thrid sentence on page 25, "you’ve change the interval to a smaller one because..." should be "you’ve changed the interval to a smaller one because..."

This section seemed fine. It is fairly easy to understand, it just has a decent amount of content to get through.

Max Demo - Ear Training for Music

This is a really cool demo and I can see it being helpful, but the scoring doesn't work again. It doesn't tell you whether your answer is correct or incorrect and your score is always 100%.
